Product Details
The Specialized Stumpjumper 15 Expert is engineered to redefine the boundaries of trail riding, offering unparalleled versatility, control, and customization. Built with a lightweight FACT 11m carbon chassis and rear-end, this bike is ready to tackle any terrain with the perfect balance of agility and stability. At the heart of this trail machine is the revolutionary GENIE Shock Technology, a patent-pending air spring system that blends the playful feel of a coil spring with the bottomless sensation of a downhill bike. This innovative design delivers 16.3% better bump absorption than traditional air shocks, giving you a ride quality that feels like you're on a much bigger bike.
The GENIE Shock also ensures 57% better traction by maintaining consistent wheel contact with the ground, providing unmatched control and confidence on rough trails. Field testing shows a remarkable 39% reduction in severe bottom-out events compared to standard FOX Float air springs, so you can push your limits without worrying about harsh impacts. Thanks to its progressive spring rate that kicks in during big hits, this shock technology eliminates compromises and offers a tunable platform for a more playful, responsive ride.
The Stumpjumper 15 Expert also features finely tuned geometry for various riding styles and conditions, boasting six-way adjustability to tailor the bike's performance to your preferences. Whether you prefer a stable ride with a slack head angle or a nimble, responsive feel, this bike adapts to your needs. For added versatility, the Stumpjumper 15 Expert accommodates different wheel setups, allowing you to choose between a full 29” configuration or a mixed-wheel setup for a more playful ride.
Additionally, the bike includes the SWAT 4.0 downtube storage system, providing sleek, weather-resistant storage to keep your essentials safe and secure on every ride. Equipped with premium components like the FOX FLOAT Performance Elite suspension with Specialized GENIE Shock Tech, SRAM GX Eagle T-Type AXS drivetrain, and SRAM Maven Bronze 4-piston brakes, this bike is built to perform at the highest level. Backed by a lifetime replacement of suspension pivot bearings for the original owner, the Stumpjumper 15 Expert is as relentless as your trail ambitions.
